19” 1U rack mount amplifier with 4 input channels and 4 independent speaker outputs. Each output can supply up to 60W to low impedance (4 or 8 ohms) or 100V speakers by connecting the top or bottom screw terminals on the rear panel. An internal media player can play audio files from a USB flash drive, tune to FM radio stations or connect via Bluetooth® to a smartphone for wireless playback of stored audio tracks. A paging microphone input has a switchable Vox function to override other channels. An additional 2 balanced inputs can be selected to accept mic or line inputs with switchable Phantom power. Channels 1 through 3 also have bass and treble controls to adjust the tone. A separate line input has RCA or screw terminal connection and, if necessary, can be switched to serve the internal media player. Each of the four inputs can be selected for one or all four output zones, all with independent output level control and a line level output for expansion to other amplifiers or powered speakers. An optional CS4 call station (953.146UK) can be added if specific area paging is required, providing a fully independent and flexible zoning system for background music, recorded information and announcements.
